I agree. I have found a diet that takes away my symptoms. However, I started taking dicyclomine for IBS. So far I have received relief from chronic abdominal pain. I still have urgency(I wear a pad so I can go out) and fecal leakage.
My colonoscopy last week was visually clear. Now waiting for biopsy results to see if I have micrscopic inflammatory disease.
I have been struggling with this for years. I have pretty much given up on a cure.

I agree. Change of diet has no effect on me either. I find stress gives me diarrhea. It is simple things like going to a doctors appointment or going to play Pickleball. I always have to know where the bathroom is. I’ve been living with us for five or so years now. I take Metamucil every day. It seems to help with going to the bathroom at the same time every day. But then again, I could have a day where I go eight times. I’ve tried everything. Lactose Free diet, gluten free diet it just doesn’t seem to matter. I am thinking about finding out if there’s some kind of medication I an take for anxiety.
